About
HARPA AI is a browser-based AI assistant and web automation platform distributed as a free Chrome and Edge extension, built to bring AI capabilities directly into everyday browsing without requiring a separate application or subscription. Founded on the principle that AI should work where users already spend their time, HARPA integrates ChatGPT, Claude, and Gemini into a unified interface that operates alongside any webpage — allowing users to summarize articles, draft emails, automate repetitive web tasks, and monitor websites for changes without leaving their browser.\n\nHARPA's feature set spans more than 100 built-in commands covering content summarization, SEO analysis, email drafting, form automation, price monitoring, and web scraping — making it one of the most comprehensive browser AI tools available. The platform's web automation capabilities allow users to record multi-step browser workflows and execute them on demand, positioning HARPA as a bridge between AI writing assistance and lightweight robotic process automation. Target users include marketers, researchers, e-commerce professionals, and knowledge workers who perform repetitive browser-based tasks daily.\n\nHARPA AI has grown to more than 400,000 active users through organic app store and word-of-mouth growth, without major institutional marketing spend. Its free-tier model has driven rapid distribution, while power users upgrade to access higher usage limits and advanced automation features. HARPA competes with browser AI extensions including Merlin and Sider but differentiates through the breadth of its command library, multi-model support, and web automation depth. The combination of AI assistance and browser automation in a zero-install extension fills a gap that neither pure AI tools nor traditional RPA platforms address.

About
Trello is a visual project management and productivity platform — operating as a product of Atlassian Corporation (NASDAQ: TEAM) since its $425 million acquisition in January 2017 — providing kanban board-based task organization to over 50 million users worldwide through its boards, lists, and cards interface that applies the Kanban methodology to individual and team project tracking. Founded in 2011 by Joel Spolsky and Michael Pryor as part of Fog Creek Software (alongside Stack Overflow), Trello launched at TechCrunch Disrupt and reached 100,000 users within six weeks. Trello spun off as an independent company in 2014, raised $10.3 million in Series A from Spark Capital and Index Ventures, and was acquired by Atlassian for $425 million — the largest acquisition in Atlassian's history at the time. In May 2025, Trello launched a major platform update introducing AI-powered task extraction (automatically creating cards from conversations and documents), Trello Inbox (collecting to-dos from Slack, Microsoft Teams, and email), Trello Planner (calendar integration for deadline management), and Mirror Cards (synchronizing tasks across multiple boards).
